摘要: A circuit has a first circuit module including a first resistor and first and second transistors coupled in parallel with the first resistor. The first resistor and the first and second transistors are coupled together at a first node. An equivalent resistance across the first circuit module increases as a voltage of the first node is increased from a first voltage to a second voltage, and the equivalent resistance across the first circuit module decreases as the voltage of the first node is increased from the second voltage to a third voltage.

摘要: Some aspects of the present disclosure provide for a method of automatically balancing mask misalignment for multiple patterning layers to minimize the consequences of mask misalignment. In some embodiments, the method defines a routing grid for one or more double patterning layers within an IC layout. The routing grid has a plurality of vertical grid lines extending along a first direction and a plurality of horizontal grid lines extending along a second, orthogonal direction. Alternating lines of the routing grid in a given direction (e.g., the horizontal and vertical direction) are assigned different colors. Shapes on the double patterning layers are then routed along the routing grid in a manner that alternates between different colored grid lines. By routing in such a manner, variations in capacitive coupling caused by mask misalignment are reduced.

摘要: A multiple-phase clock generator includes at least one stage of dividers. A clock signal is supplied as a first stage clock input to dividers in a first stage of dividers. An N-th stage includes 2N dividers, where N is a positive integer number. Each divider in the first stage is configured to divide a first clock frequency of the first stage clock input by 2 to provide a first stage output. Each divider in the N-th stage is configured to divide an N-th clock frequency of an N-th stage clock input by 2 to provide an N-th stage output. The N-th stage outputs from the dividers in the N-th stage provide 2N-phase clock signals that are equally distributed with a same phase difference between adjacent phase clock signals.
